### Calling Sequence

  `newname=edit(functionname [, editor])`

### Parameters

- `functionname`: character string
- `editor`: character string

### Description

If functionname is the name of a defined scilab function `edit(functionname ,[editor])` try to open the associated file `functionname.sci`. If this file can't be modified `edit` first create a copy of this file in the TMPDIR directory.

If functionname is the name of a undefined scilab function `edit` create a functionname.sci file in the TMPDIR directory.

When leaving the editor the modified or defined function is loaded into Scilab under the name `newname`.

The editor character string can be used to specify your favourite text editor. It is generally a system command, or the string "scipad", in which case the internal editor is used.

Default editor is Emacs. This function should be customized according to your needs.
